A high clearance self-propelled sprayer was designed, and a 3D model of sprayer frame was built with CATIA. Its finite element model was built by using Hypermesh, and it was imported to ABAQUS for finite element analysis. The analysis researched the stress and deformation of frame under four typical conditions of constant-velocity, torsion, emergency braking and emergency turning. The weak region of strength in the variable track mechanism was found, and a size optimization research was carried to the square pipe of the variable track mechanism. The result showed that the maximum stress of frame after optimization decreased obviously, and the distribution of stress became much more reasonable. The optimization ensured the reliability of the frame design.

This paper is based on some curved wide extra-dosed cable-stayed bridge, and the finite element software MIDAS/CIVIL is applied to set up three different system models of semi-floating system, pylon-girder consolidation system and rigid frame system according to the practice engineering background. Compared the internal forces and displacements in three systems under dead load, temperature load and live load, conclusions can be drawn as, the overall stiffness of rigid-frame system is the largest, its deformation is the least under dead load and live load, but it is sensitive to temperature load which can cause large second internal force. According to the overall structure performance of three different systems, it is better understanding their superiority to different application range, which can be a reference for designing in the future.

Internet gambling crimesas same to general gambling crimes is a complex social phenomenon. And it present fast development, a wide range of effect and deep degree of harm. According to the characteristics that it is diffculty to find investigation and eradicate in practice. The investigation should find it difficult for online gambling crime, investigation and evidence we should strengthen awareness initiative investigation about the investigation uncover clues.Adopt a multi-force investigation coordinated operations multisectoral ideas, strengthen the investigative mechanism about related cases andeffectively combat internert gamblingcrimes.

The reliability of supply chain network system design and optimization based on the industrial cluster was discussed, that is, the operational platform of multi-objective supply chain network was moved to industrial cluster, so the platform has the effects of both regional radiation and scale of economy. Instead of some static research methods such as former traditional mathematic planning, systematic and dynamic analysis, this paper put forward a coordinative mechenism construction, this mechenism used dynamic simulation method which combined the supply chain system with industrial cluster multi-objective weighing in the region, the mechenism should be cost efficient and satisfy the application in the industrial cluster radiation region, the mechenism should integrate all possible resources in the industrial cluster and consider heterogeneity, layout, nonlinear, limitation and dynamics of the supply chain network system.

By introducing some atmospheric models and selecting methods for minimum integration step size and optimum initial integration value, a program of real time and near real time landing point predicting together with weighted processing methods of many groups of landing point parameters were put forward. Engineering application showed: the above methods and program improved real time and near real time landing point predicting precision more greatly compared with previously used methods, which had proved their broad applicability.

In MANET, MSWCA is a typical algorithm in clustering algorithms with consideration on motion-correlativity. Aiming at MSWCA’s problem that “it only considers on intra-cluster stability, and neglects the inter-cluster stability”, a MANET-based stable clustering algorithm (MSCA) was proposed. Firstly, MSCA clustering algorithm and its cluster maintenance scheme were designed. Secondly, the theoretical quantitative analyses on average variation frequency of clusters and clustering overheads were conducted. The results show that MSCA can improve cluster stability and reduce clustering overheads.

Through batch-enrichments from contaminated sea-bed mud in Bohai sea we have isolated and characterized two bacterial strains named T7-2 and T7-7 that can better use hydrocarbons as a source of carbon and energy at 15°C than others. The mixed bacteria was used to degraded diesel oilGudao light crude oil from Shengli Oilfield and Guan 69-8 heavy crude oil from Dagang Oilfield then the degradation rates were 81.11%, 97.05% and 61.08%.

There are 5 kinds of bus networks on armored vehicles. The current vehicle serial bus test equipments are not universal to different kind bus system. And can just complete the performance test to DLL, cannot test the buss physical electrical performance. This paper brings forward a new data acquisition method to universal buses based on software decoding, The data acquisition experiments to CAN and 1553B bus with their corresponding bus nodes have been completed.

Nowadays, the use of new energy increasing attention has been paid. In response to the current situation of shortage of energy, people will treat photovoltaic inverter as a new power supply. In order to improve the utilization of solar energy, the single-phase photovoltaic inverter power grid and the public grid operation. It is important that the effective control in the process of grid Inverter for solar. Lack of the PID strategy in the grid control, model reference adaptive control is improved.

The paper proposed a simulating arbitrary slip surface method. For simulating slip surface, select 7 control points, then connect to broken line which is assumed slip surface. Horizontal spacing between 7 control points is not equal, the spacing is arbitrary. Horizontal spacing of general simulating slip surface method is equal. So the proposed method is closer to the actual. For search method, particle swarm algorithm is not easy to fall into local minima, as a global intelligent optimization method, particle swarm algorithm is suitable for search the most dangerous slip surface. Based Janbu method, the paper computed two examples for simple slope and complex slope. The results show that the proposed method is effective.

During the flight of the hypersonic Vehicle, the angle of attack will change with the flight attitude. At the same time, the aerodynamic forces from the surface of aircraft will also be changing. The pressure and friction force are the main causes of the aerodynamic heating, so the surface aerodynamic heating will change. By used the method of numerical calculation, the passage studied the influence the change the pressure and friction force on the distribution of heat flux in different angle of attack and the relationship between the change of the force of lift-drag and aerodynamic heating. The research suggested that the distribution of the heat flux had very good consistency with that of pressure and friction. The lift change was the dominant factors influence of pneumatic thermal change; the change of drag force affected only the speed of heat flux change.
